Glad to hear indeed.
I had similar findings when switching from to 4 shamans + warrior to 3 shamans + warrior + priest to a full multiclass group.

Errrr .... I mean ... you're completely wrong! :P

[edit]
My current setup possibilities are:

[warrior/priest/shaman] + [mage] + [shaman] + [hunter] + [druid]
I'm currently mostly active with the warrior(80) as tank and druid(68) as healer. This way I can get some tanking gear for the druid by doing instance boosting.
